pflash: fix sectors vs bytes confusion in blk_pread_nonzeroes()
The following expression is incorrect because blk_pread_nonzeroes()
deals in units of bytes, not sectors:
bytes = MIN(size - offset, BDRV_REQUEST_MAX_SECTORS)
^^^^^^^
BDRV_REQUEST_MAX_BYTES is the appropriate constant.
Fixes: a4b15a8b9ef2 ("pflash: Only read non-zero parts of backend image")
